Opendkim as a daemon as something added to an existing smtpd with postfix is not that complicated.

This feels like shifting the goalposts. From "one line in DNS" to "just install extension into your email daemon and configure it."

Your e-mail daemon should already have configuration for DKIM, and the same tool that generates that key should also print out the complete DNS entry you need. Configuring DKIM in your daemon is a bit of work; The DNS portion of it is simple.

If a person is trying to self-host their own MX and doesn't want to get into the details of configuring SPF, DKIM and DMARC, I would highly recomment they go with something like gsuite or office365 instead. Or some other managed email hosting provider that will do the DKIM setup for them.
